[0045] like Figures 1 to 5As shown, this embodiment provides a diverting loading mechanism, comprising a loading unit 100, a conveying unit 200, and a diverting unit 300. The diverting unit 300 comprises a diverting plate 301 and a first driving unit 302 for driving the diverting plate 301 to rotate and elevate. The diverting plate 301 is provided with a plurality of through-holes 3011. The conveying unit 200 comprises a first roller 2011 and a second driving unit 2013 for driving the first roller 2011 to rotate. The first roller 2011 is arranged perpendicular to the plane where the diverting plate 301 is located. The loading unit 100 is located on one side of the conveying unit 200. The loading unit 100 is used to transfer objects to the diverting plate 301 when it is in a raised state. When the first driving unit 302 drives the diverting plate 301 to descend, the first roller 2011 can at least partially pass through the through-holes 3011 of the diverting plate 301.

[0046] The diverting loading mechanism provided in this embodiment is applied to PCBs on an automated production line. The loading unit 100 transports the PCBs to the conveyor unit 200, where they are transferred to the next process. As the PCBs are transported from the loading unit 100 to the conveyor unit 200, the diverting plate 301 of the diverting unit 300, driven by the first drive unit 302, rises, positioning the diverting plate 301 above the first roller 2011 of the conveyor unit 200. The loading unit 100 then transports the PCBs onto the diverting plate 301. At this point, if the PCB needs to be diverted according to the process requirements, the steering plate 301 rotates under the drive of the first drive unit 302, thereby driving the PCB on the steering plate 301 to steer. After the steering plate 301 is steered, it descends under the drive of the first drive unit 302. During the descent of the steering plate 301, the first roller 2011 of the conveying unit 200 at least partially passes through the through hole 3011 in the steering plate 301, causing the first roller 2011 to contact the PCB on the steering plate 301. The PCB moves to the next process under the drive of the first roller 2011. This operation mode eliminates the need to first transport the PCB and then steer it when the PCB needs to be diverted. Instead, the transport and steering processes are integrated into a single module, streamlining the automated production line and reducing floor space.

[0047] At the same time, the PCB board can be conveniently transported and turned by the coordinated transmission method of the steering plate 301 and the conveying unit 200. For example, the loading unit 100 is configured to transport the PCB board in the horizontal direction, and the conveying unit 200 is configured to transport the PCB board in the vertical direction. When the PCB board is transported, the loading unit 100 transports the PCB board in the horizontal direction to the steering plate 301 in the raised state, and then the steering plate 301 is driven by the first driving unit 302 to descend, so that the PCB board on the steering plate 301 contacts the first roller 2011 of the conveying unit 200, and the first roller 2011 drives the PCB board to be transported in the vertical direction. In this process, the direction of transportation of the PCB board can be switched regardless of whether the PCB board itself needs to be turned. It can make the construction of the automated production line more flexible, and reasonably allocate the distribution of each module of the automated production line according to the site of use. Such a setting method can also improve the loading efficiency, for example Figure 1 As shown in , there are at least one pair of loading units 100, with the two loading units 100 in each pair being located on opposite sides of the conveying unit 200, and the transmission direction of each loading unit 100 being perpendicular to the rotation direction of the first roller 2011. Because the loading direction and the transmission direction are perpendicular to each other, loading units 100 can be installed on both sides of the conveying unit 200. This prevents the two loading units 100 from interfering with each other during the loading process, thereby improving loading efficiency.

[0048] For the first driving unit 302, as Figure 3 As shown in , the first driving unit 302 includes a first driving member 3021 and a second driving member 3022. The first driving member 3021 is mounted on the second driving member 3022, and the steering plate 301 is mounted on the first driving member 3021. The first driving member 3021 drives the steering plate 301 to rotate, and the second driving member 3022 drives the first driving member 3021 to move up and down, thereby driving the steering plate 301 to move up and down.

[0049] For example, the first driving member 3021 may be a rotary cylinder, and the second driving member 3022 may be a linear cylinder.

[0050] For example, for the transmission unit 200, Figure 4 and Figure 5As shown, the conveying unit 200 includes a first conveying portion 201. The first conveying portion 201 includes a plurality of connecting shafts 2012, a plurality of first rollers 2011, and two parallel vertical plates 2015. The plurality of connecting shafts 2012 are parallel and spaced apart and connected between the two vertical plates 2015. The connecting shafts 2012 are rotatable between the two vertical plates 2015. The plurality of rollers are disposed on the connecting shafts 2012 and spaced apart on the connecting shafts 2012. Among them, the connecting shaft 2012 located in the middle is shorter, and one end of the connecting shaft 2012 located in the middle is rotated to connect to the vertical plate 2015, and the other end thereof is passed through the bearing located in the bearing seat 2014. A gap 203 is formed between the two shorter connecting shafts 2012, and the first driving unit 302 of the steering unit 300 passes through the gap 203 so that the steering plate 301 of the steering unit 300 is located above the connecting shaft 2012, and the steering plate 301 can be lifted and lowered so that the first roller 2011 of the transmission unit 200 at least partially passes through the through hole 3011 of the steering plate 301, thereby contacting the PCB board on the steering plate 301.

[0051] For example, for the second driving unit 2013 of the transmission unit 200, as shown in FIG. Figure 5 and Figure 6 As shown, the second driving unit 2013 includes a first motor 20131, a first pulley 20132, a conveyor belt 20134, a second pulley 20133, a connecting rod 20136, a plurality of first magnetic wheels 20135, and a plurality of second magnetic wheels 20137. The first pulley 20132 is installed on the output end of the first motor 20131, and the conveyor belt 20134 is sleeved on the first pulley 20132 and the second pulley 20133. When the first motor 20131 drives the first pulley 20132 to rotate, the first pulley 20132 drives the second pulley 20133 to rotate through the conveyor belt 20134. The connecting rod 20136 is connected to the middle part of the second pulley 20133, and the first magnetic wheel 20135 is sleeved on the connecting rod 20136. When the second pulley 20133 rotates, it drives the connecting rod 20136 to rotate and then drives the first magnetic wheel 20135 located on the connecting rod 20136 to rotate. The second magnetic wheel 20137 is mounted on one end of the connecting shaft 2012 of the transmission unit 200. During rotation, the first magnetic wheel 20135 uses magnetic force to drive the second magnetic wheel 20137, which in turn drives the connecting shaft 2012 of the transmission unit 200, thereby driving the first roller 2011 mounted on the connecting shaft 2012. This non-contact transmission method reduces equipment wear and noise.

[0052] Furthermore, when the PCB board is transported from the loading unit 100 to the steering plate 301 in the raised state, in order to facilitate the movement of the PCB board on the steering plate 301, as shown in FIG. Figure 4and Figure 7 As shown in , the conveying unit 200 further includes a second conveying portion 202, which includes a second roller 2021 and a third drive unit 2022 for driving the second roller 2021 to move upward and downward. The second roller 2021 is arranged perpendicular to the plane of the deflection plate 301. The rotation direction of the second roller 2021 is consistent with the direction in which the loading unit 100 conveys materials. When the second roller 2021 is driven to move upward and downward by the third drive unit 2022, the second roller 2021 can at least partially pass through the through hole 3011 of the deflection plate 301. When the PCB board is moved from the loading unit 100 to the steering plate 301, the second roller 2021 rises under the drive of the third driving unit 2022. At this time, the second roller 2021 at least partially passes through the through hole 3011 of the steering plate 301, so that the second roller 2021 contacts the PCB board on the steering plate 301. The PCB board runs on the second roller 2021 and moves smoothly to the steering plate 301, avoiding damage to the PCB board. After the PCB board is moved into position on the steering plate 301, the second roller 2021 is driven by the third drive unit 2022 to descend, and the second roller 2021 moves to the bottom of the steering plate 301 and is located below the first roller 2011. At this time, the PCB board on the steering plate 301 is disengaged from the second roller 2021, and the steering plate 301 is driven by the first drive unit 302 to descend, so that the PCB board on the steering plate 301 contacts the first roller 2011 of the conveying unit 200, and the conveying unit 200 transports the PCB board to the next process.

[0053] Specifically, the conveying unit 200 further includes a plurality of mounting plates 2024, on which the plurality of second rollers 2021 are mounted. The mounting plates 2024 are provided with a plurality of grooves 20241 at intervals, thereby forming a plurality of mounting positions between the grooves 20241. The second rollers 2021 are rotatably mounted in these mounting positions. The plurality of mounting plates 2024 are spaced apart and spaced apart from the plurality of connecting shafts 2012 of the conveying unit 200. The third drive unit 2022 drives the mounting plates 2024 to rise and fall simultaneously.

[0054] Exemplarily, the third driving unit 2022 may be a linear cylinder.

[0055] At the same time, in order to facilitate the steering plate 301 of the steering unit 300 to rotate, the PCB located on the steering plate 301 is offset or falls off during the rotation of the steering plate 301. Figure 8 and Figure 9As shown, the steering unit 300 also includes a pressure plate unit 400, which includes a pressure plate 405 and a pressure plate driving unit. The pressure plate 405 is located above the steering plate 301, and the pressure plate 405 can be raised and lowered above the steering plate 301 under the drive of the pressure plate driving unit. When the steering plate 301 rotates under the drive of the first driving unit 302, the pressure plate 405 can fit with the object on the steering plate 301 and the pressure plate 405 can rotate together with the steering plate 301.

[0056] By cooperating the pressure plate 405 of the pressure plate unit 400 with the steering plate 301 , the PCB board on the steering plate 301 can be stably located on the steering plate 301 when the steering plate 301 rotates, and will not deviate or fall off on the steering plate 301 .

[0057] Specifically, such as Figure 9 As shown, the pressure plate unit 400 includes a first power source 401, a second power source 403, a connecting block 402, an elastic return member 404, and a pressure plate 405. The second power source 403 is mounted on the first power source 401 via the connecting block 402. The first power source 401 can drive the second power source 403 to move linearly. The pressure plate 405 is mounted on the second power source 403. The second power source 403 can drive the pressure plate 405 to rotate. One end of the elastic return member 404 is connected to the connecting block 402, and the other end of the elastic return member 404 is connected to the pressure plate 405. When the steering plate 301, which carries the PCB, rotates, the first power source 401 drives the second power source 403 toward the steering plate 301, which in turn drives the pressure plate 405 toward the steering plate 301. The pressure plate 405 stops moving when it contacts the PCB on the steering plate 301. When the steering plate 301 rotates, the second power source 403 drives the pressure plate 405 to rotate along with the steering plate 301, ensuring that the PCB located between the pressure plate 405 and the steering plate 301 is securely positioned on the steering plate 301 and prevents it from shifting or falling off. The elastic return member 404 acts as a buffer, ensuring that the rotation of the pressure plate 405 and the steering plate 301 are consistent.

[0058] For example, the first power source 401 may be a linear cylinder, the second power source 403 may be a rotary cylinder, the elastic return member 404 may be a spring, and the spring is sleeved on the connecting block 402, which is cylindrical.

[0059] In summary, the steering loading mechanism provided in this embodiment integrates the conveying unit 200 and the steering unit 300 into one, streamlining the automated production line and reducing the site space occupied. In addition, by raising and lowering the steering plate to bring the PCB board into contact with the first roller of the conveying unit, the conveying route of the PCB board can be freely designed, thereby achieving higher conveying efficiency.

[0060] On the other hand, Figure 10 As shown in , this embodiment further provides a PCB board loading machine, including a frame 1 and the steering loading mechanism as described above, the steering loading mechanism is installed on the frame 1, and the steering loading mechanism is used to operate the PCB board.

[0061] Furthermore, if Figure 10 and Figure 11 As shown, the PCB board loading machine provided in this embodiment also includes a clapperboard alignment mechanism 500, which includes a first sliding base 501 and an alignment portion 502 slidably mounted on the first sliding base 501. The first sliding base 501 is located above the loading unit 100, and the alignment portion 502 drives the object from the loading unit 100 to the deflection plate 301. The clapperboard alignment mechanism 500 drives the PCB board from the loading unit 100 to the deflection plate 301 above the conveying unit 200, thereby facilitating the control of the rhythm of the PCB board's movement toward the loading unit 100. When two loading units 100 are set on both sides of the conveying unit 200, PCB boards can be prepared on both loading units 100 in advance, and then the PCB boards on the two loading units 100 are driven one by one onto the conveying unit 200 through the approximation plate alignment mechanism 500. After one PCB board is turned and transported to the next process by the transfer unit, the approximation plate alignment mechanism 500 drives the PCB board on the other loading unit 100 onto the steering plate 301.

[0062] Specifically, such as Figure 11 and Figure 12 As shown, the clapper alignment mechanism 500 includes a first sliding base 501, two second motors 503, and two alignment parts 502. The two alignment parts 502 are respectively located at opposite ends of the first sliding base 501. The two second motors 503 respectively drive the two alignment parts 502 to move linearly on the first sliding base 501. The linear movement driven by the second motors 503 is a mature technology and will not be described in detail here. The alignment part 502 includes a sliding part 5021, a connecting part 5022, and a pushing part 5023. The alignment part 502 is slidably mounted on the first sliding base 501 via the sliding part 5021. The connecting part 5022 is located between the pushing part 5023 and the sliding part 5021. The pushing part 5023 includes a plurality of pushing blocks, which are spaced apart on the connecting part 5022. A plurality of third rollers 101 are provided on the loading unit 100. When the PCB board is located on the loading unit 100, the PCB board contacts the plurality of third rollers 101. When the alignment portion 502 of the aligning mechanism 500 moves on the first sliding base 501, the pushing portion 5023 of the alignment portion 502 pushes the PCB board on the third rollers 101 of the loading unit 100 to move onto the steering plate 301 above the conveying unit 200.

[0063] like Figure 13As shown, the PCB board loading machine provided in this embodiment also includes two feeding mechanisms 600. The feeding mechanism 600 includes a second sliding base 602 and a loading portion 601 slidably mounted on the second sliding base 602. The loading portion 601 is mounted on the second sliding base 602 in a liftable manner. The two feeding mechanisms 600 are respectively installed corresponding to the two loading units 100. The loading portion 601 of the feeding mechanism 600 slides on the second sliding base 602 to above the loading unit 100, and the loading portion 601 is lifted and lowered to place the object on the loading unit 100. This allows the PCB board to be loaded onto the loading unit 100 without interfering with the third roller 101 of the loading unit 100.

[0064] Specifically, the feeding mechanism 600 includes a second sliding base 602, a sliding block 604, a connecting plate 605, a loading unit 601, and a third motor 603 and a fourth motor 606. The third motor 603 drives the sliding block 604 to slide on the second sliding base 602, the connecting plate 605 is fixedly connected to the sliding block 604, and the fourth motor 606 drives the loading unit 601 to rise and fall on the connecting plate 605. The driving methods of the third motor 603 to drive the sliding block 604 to move linearly on the second sliding base 602 and the fourth motor 606 to drive the loading unit 601 to move linearly on the connecting plate 605 are mature technologies and will not be described in detail here.

[0065] like Figure 14 and Figure 15 As shown, the loading unit 100 also includes a fourth driving unit 105 for driving the third roller 101 to rise and fall, a loading plate 102, a vertical plate 104 and a plurality of bearing parts 103, the plurality of bearing parts 103 are arranged at intervals in a direction gradually approaching or away from the conveying unit 200, a first interval 1031 is formed between the plurality of bearing parts 103, a plurality of grooves 1021 distributed at intervals are formed on the loading plate 102, the third roller 101 is rotatably installed on the protrusion formed between the plurality of grooves 1021 on the loading plate 102, the plurality of bearing parts 103 are respectively located in the grooves 1021 of the loading plate 102 and are fixedly installed on the frame 1 through the vertical plate 104, so that the plurality of third rollers 101 are respectively located in the first intervals 1031 of the plurality of bearing parts 103. The loading portion 601 can gradually move toward or away from the loading unit 100 on the second sliding base 602 in a direction perpendicular to the arrangement of the supporting portions 103. This is achieved by arranging the sliding direction of the loading portion 601 on the second sliding base 602 to be along the extension direction of the intervals between the supporting portions 103. The loading portion 601 and the third roller 101 are spaced apart in the intervals between the multiple supporting portions 103. The third roller 101 can be driven up and down by the fourth driving unit 105, which can adapt to the height of the steering plate 301 and provide greater flexibility.

[0066] Specifically, the loading unit 100 further includes a support plate 106, two cross bars 107, and two vertical bars 108. The support plate 106 is connected to the fourth drive unit 105, which drives the support plate 106 to rise and fall. The two cross bars 107 are mounted on the support plate 106 in parallel with each other, and the two vertical bars 108 are mounted at both ends of the cross bars 107 perpendicular to the cross bars 107. Multiple loading plates 102 are mounted on the two vertical bars 108 in parallel and spaced apart. The fourth drive unit 105 drives the support plate 106 to rise and fall, thereby driving the multiple loading plates 102 to rise and fall simultaneously, thereby causing the multiple third rollers 101 to rise and fall simultaneously.

[0067] Exemplarily, the fourth driving unit 105 may be a linear cylinder.

[0068] At the same time, if Figure 10 、 Figure 13 and Figure 14 As shown, the loading portion 601 includes at least two L-shaped support rods. Multiple loading units 100 are spaced apart on one side of the conveyor unit 200, forming a second interval 1032 between the multiple loading units 100. At least two support rods are located in the second intervals 1032 of adjacent loading units 100. The support rods are divided into a connecting section 6012 and a supporting section 6011 at the bend. The connecting section 6012 is movably mounted on the second sliding base 602, and the supporting section 6011 extends perpendicular to the rotation direction of the third roller 101.

[0069] The working process of the PCB board feeder provided in this embodiment is further explained in combination with the above structure:

[0070] When the PCB board is put into the automated production line, the loading part 601 of the feeding mechanism 600 moves on the second sliding base 602 in the direction away from the loading unit 100. After the loading part 601 moves into position, the PCB board is placed on the supporting section 6011 of the support rod of the loading plate 102 of the feeding mechanism 600. Then the loading part 601 moves on the second sliding base 602 toward the loading unit 100. The loading plate 102 moves to the loading unit 100 and the support rod is located in the second interval 1032 between adjacent loading units 100. The loading plate 102 descends on the second sliding base 602, so that the PCB board on the support rod contacts the third roller 101 of the loading unit 100. Then, the alignment part 502 of the aligning mechanism 500 drives the PCB board to move on the third roller 101 of the loading unit 100 toward the conveying unit 200. At this time, the steering plate 301 rises, so that the through hole 3011 of the steering plate 301 is separated from the first roller 2011 of the conveying unit 200. At the same time, the second roller 2021 rises and passes through the through hole 3011 of the steering plate 301. The PCB board is moved from the loading unit 100 to the steering plate 301 through the alignment part 502. During this period, the PCB board is transported by the third roller 101 of the loading unit 100 and the second roller 2021 of the conveying unit 200. After the PCB board is completely moved onto the steering plate 301, the second roller 2021 descends and separates from the steering plate 301. If the PCB on the steering plate 301 does not need to be adjusted, the steering plate 301 moves downward, allowing the first roller 2011 of the conveyor unit 200 to pass through the through-hole 3011 of the steering plate 301, bringing the first roller 2011 into contact with the PCB on the steering plate 301. The PCB is then conveyed to the next process step by the first roller 2011. If the PCB on the steering plate 301 needs to be adjusted, the pressing plate 405 of the pressing plate unit 400 descends and engages with the PCB on the steering plate 301. The steering plate 301 rotates to adjust the PCB's orientation. After the PCB is adjusted, the pressing plate 405 ascends and disengages from the PCB. The steering plate 301 then descends, allowing the first roller 2011 of the conveyor unit 200 to partially pass through the through-hole 3011 of the steering plate 301 and contact the PCB. The PCB is then conveyed to the next process step by the first roller 2011.

[0071] In summary, the PCB board loading machine provided in this embodiment integrates the conveying unit 200 and the steering unit 300 into one, which simplifies the automated production line and reduces the floor space, and has higher PCB board loading and operation efficiency.

[0072] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
